There was a problem in rrc_gNB_process_NGAP_PDUSESSION_RELEASE_COMMAND()
where we PROTOCOL_CTXT_SET_BY_INSTANCE() that does not initialize
eNB_index leading to a crash later on in pdcp. So let's initialize
everything.

Plus, while we're here, use do { } while(0) in the macros, just to avoid
problems like:

  if (condition)
    macro;

Without do { } while(0) only the first statement of the macro is done
in the if. (Not sure if the code has the problem somewhere, but doesn't
hurt to fix.)

- Mention python version and separate Python/own modules
- Use constants for registry and namespace name
- Provide OC url in oc login
